Where is the buffer board on my Samsung Plasma TV.,

Plasma TV's are very difficult to repair. You will need a power supply....and two buffer boards. The buffer boards are on the left and right. If you install the power supply only.......the buffer boards will take it down. And the Y board is not out of the question. The headache and expense is not worth the repair. I just saved your stress. By all means recycle this and buy new. Thanks for asking, Matt of Martins TV.

In most of the case is the data buffer located on the lower bottom of the Plasma panel is damaged duo to defective buffer IC, or it was damaged by leaky liquid dripped to it. Some older panels you may change the buffer board, but newer panel, the buffer board is directly soldered to the panel by a few flat flex cable, you can not change it.

It is possible that the buffer board will fix your problem, but try removing, cleaning and reseating the flex cables between the buffers and the panel first. All it takes is a little bit of dirt or oxidation to open a connection and cause a line-out condition. Use a lint free cloth and a little bit of alcohol to clean them. Make sure to fully insert the cables and center them perfectly in the connectors or you will have even more lines. If the original line is still there after cleaning, then try replacing the board. Buy a board from a reputable dealer that will guarantee no problems with the board. If you still have the line even after changing the board, then the plasma panel has failed and the only fix is to replace the panel.
Always let the tv set for an hour unplugged before attempting any repair work. There are dangerously high voltages in plasma tvs that can cause severe shocks or even *****.

Contact the authorized service center for Samsung. That is the only thing you can do.

Vertical lines on a plasma TV are caused by either a failing x-buffer board or a loose connection at the flex cable between the panel and the buffer board. Sometimes just removing the flex cable, cleaning it, snd reinstalling it will fix it.

Tries unplug,replug the cable or satalite boxes back like about an hour later,for those pay boxes to reboot and upgraded it software,tv now might work again,but if still have the same problems.The tv X or Y buffers boards are dead or both.These 2 long buffers boards are to the right and to the left of the tv to provide the tv Plasma screen panel to have a backlight to produce a picture on the tv Plasma screen panel.Try website like Ebay.com to buy those 2 long refurbishes X or Y or both long buffers boards for the replacement.

I had this issue..Go to Menu and go to the burn in troubleshooting and run the scrolling feature..Scrolls whites and darks..Run for an hour..I had it on both sides..From watching 4 X 3 pic, image retention..Should clean up fine

bad y buffers , your model may have only one y buffer and you may need a Y main too. voltage checks can confirm VS and VA voltages marked on board plugs and tag inside TV

I have a Phillips 50 inch Plasma. About two months out of warranty the top half of the screen would go black. Sometimes when we tapped on the back behind the upper right hand corner the picture would return. I did some research online and found that there is a Main Y sustain board (much like a mother board in a computer) and connected to that board is a upper Y Buffer board and a Lower Y buffer board. According to my research these boards seem to be the source of the problem. I am assuming that the upper buffer controls the top half of my screen and the lower controls the bottom. I removed the back of my TV (about 50 small screws) and searched for these parts by part number. Surprisingly all of the parts in my Phillips are made by Samsung. I found the parts on ebay at shopjimmy.com. I decided to try replacing the upper Y buffer first. I ordered it from shopjimmy for about 100.00. When I received the part I started to remove my upper Y buffer and realized that the new part was slightly different. The part number was the same but the REV. number was slightly different. The new part was missing a small white connector that connects the upper buffer to the lower buffer. I sent it back for an exchange for the right part with no problem. Ok so here is the interesting piece of this little adventure. When I started to remove my upper Y buffer I removed the screws and started to pull on it to loosen it. When I noticed that I had the wrong part I pushed it back into place and put the screws back . My TV has worked perfectly since I did that, with my original part. It has only been about two months, but if you are in the same situation it might be worth a try.
